[Samba] Kerberos issue after upgrade

I recently upgraded samba on a domain controller from
samba3-3.3.4-39.el5 to samba3-3.3.6-39.el5 (from SerNET on a CentOS 5.3
box), and the interdomain trusts between the samba domain and my AD
domain quit working.  

The /var/log/samba/wb-ADDOMAIN file was full of this message:
[2009/07/02 09:19:57,  0] libads/kerberos.c:ads_kinit_password(362)
  kerberos_kinit_password SAMBADOMAIN at ADDOMAIN.UNIVERSITY.EDU failed:
Cannot find KDC for requested realm

Even though the Samba-HowTo says that configuring your krb5.conf file
may be detrimental, I did so anyway.

After configuring my krb5.conf, winbind was able to resolve users from
the AD domain.
